HYDROGEN EVOLUTION: THE EFFECT OF SURFACE CONCENTRATION

Abstract

It is shown that the mechanism of the mechanism of the hydrogen evolution reaction is rate-determining discharge followed by Tafel recombination at low overpotential, and electrochemical desorption at high overpotentials (> 600 mv). These conclusions are also in harmony with the findings of Frumkin (1957), who used a qualitative method of establishing the mechanism, by observing the increase or decrease of overpotential at constant current when additional amounts of hydrogen are introduced by permeation.
